I was the attending flight surgeon on that crash. The description is accurate except in two respects: The pilot in the jump seat was a student and it was the aircraft commander not the copilot who also perished, but not because his seat malfunctioned. The gang ejection function on the B-1B went in a specific order: #1 was the rightseat pilot, then the Defensive Systems Officer, then the Offensive systems officer, finally the leftseat pilot (AC). The aircraft impacted the ground before his ACESII seat had time to activate.
Neither of the jumpseat occupants had a prayer and after that crash, low level missions were restricted to 4 crew only.
ACESII was/is a good seat, I wondered about that when I read the link. Thanks for setting the record straight.
Thanks for that discussion.
